Hi,

I would like to ask if anyone has made the experience of migrating an existing Hibernate 2.1 Mapping to Hibernate 3?

My situation is the following:
We have a legacy database schema mapped with Hibernate 2.1 and built a webapp (Webmail) on top of this.
Now we are going to build a second application on top of the same schema.
The new app will be based primary on different tables than the first, but many tables are the same.

So would you recommend to move the schema to Hibernate 3 and start developing on top of it (and later maybe migrate the older application, too)?
Are there any really compelling improvements in Hibernate 3 to justify this?
